When a 2.67 g sample of solid sodium hydroxide dissolves in 75.0 g of water in a coffee cup calorimeter the temperature increases from 19.8 to 28.9^oC. Calculate the ÎH in kJ/mol for the dissolving of NaOH in water. Assume that the specific heat of the solution is the same as that of pure water (4.184 J)
